    Any one else use these RR spring clips? 20180507_204040.jpg

    About 3 hours straightening with a 4 lbs sledge.

    They provide a great spark with testing. I've made a few knives from some of them, but I was wanting to know someone else has worked with 'em.:)

    I have not worked with the spring clips but I've heard they are good knife steel.

    I have a bunch of these these but haven't tried working them yet because I've heard they are so hard to straighten.

    It's a big hunk of steel to get moving. It's not too bad once you get it down to about 1/4 inch.

    There are a lot of knives in one clip.

    I made a giant Bowie out of some track that a guy gave me years ago to use as my first anvil. I forged the guard from a railroad spike. I used it to win a cutting contest on Facebook.

    That's elk antler for the handle and I heat blued the guard.

    I've tried forging the kind you have there. I think I got as far as straightening...Tough stuff!

    But I have also found these other clips near certain railroads. They're already in a convenient shape and size. I forged one into a blade and got my first hamon with it. That was quite a few years ago.

    Get it good and hot ! Just don’t over heat it and swing hard ! The ones we sent out for testing where 1095 . Don’t bother with spikes they are pot metal .

    Well, spikes aren't too bad fo holding down track :)rolleyes:). The "high carbon" spikes are alloyed with a bit more carbon than regular spikes, for what purpose I don't know.

    They are good for forging but not anything that requires edge retention. The alloy waa developed to increase the toughness of the steel. The formulation allows for wide temperature variations with out issues from thermal stresses.

    It would be better for the spike to bend slightly than to crack and shear.

    Thanks for the alloy ID. I gotta ask, how did you get it lab tested. I've often wondered how non-industry folk go about having this done.:33:

    I spoke with a person down here in Alabama that works at one of the places that manufactures the railroad spikes. He has first hand experience and knowledge with dog spikes being pot metal and med carbon steel at best . He said that some of them will contain more carbon than than others but there is not an exact recipe for those. The Clips and springs have to be made of good steel so the track can flex on bends , turns and then return true . One of the fellows at our forge is an engineer for miller welders. He was the one that Had them sent out to be texted so I’m not sure but I can find out .

    I understand that some spikes have a "large" amount of copper alloyed in them. I don't know why. I can believe "pot metal". I wonder if that term means "pot luck"; whatever is left over in the pot.

    That way no expensive formulations to be made along with testing, just tranfer remnant from pot "A", "B"and"C" to pot "D", blend, then pour for extrusion for billeting.

    That would explain the lasai faer manner in which they are cast about the tracks. I counted better than 20 spikes along a quarter mile of track. I wonder what kind of steel those big screws are?

    I have a few but haven't tried forging them yet. I'll have to give it a try.
